RESUMO

In the United States, the majority of early breast cancer patients choose breast-conserving treatment in the community setting, yet there is a paucity of literature describing outcomes. In this paper, we describe our experience with breast-conserving treatment in a small community hospital. Our hospital tumor registry was used to identify breast cancer cases diagnosed at our hospital between 1997 and 2003. We limited our study to those women with initial attempts at breast-conserving surgery (BCS) who had follow-up oncology treatment at on-campus affiliated oncological services. We looked at factors that influence survival for early stage 0-II disease such as tumor and patient characteristics, completeness of local surgical tumor excision, and adjuvant treatment. We also evaluated the percentage of cases in which the initial BCS did not achieve adequate surgical oncological results and the number and type of subsequent surgeries that were required to achieve this goal. There were 185 cases with a median patient age of 55 and a median follow-up time of 53 months. Most tumors were stage 0-I (68%) or stage II (23%). A single surgery was deemed sufficient to achieve the desired oncological outcome in 54% of cases; the remaining cases (46%) required additional surgeries. A final margin of 5 mm or greater was successfully achieved in 81% of cases. Ninety-two percent of the patients underwent radiotherapy, 65% received hormonal therapy, and 49% underwent chemotherapy. One hundred and sixty one patients had successful breast-conserving surgeries (87%) and 24 patients (13%) ultimately required mastectomy. There were four loco-regional recurrences and 19 deaths during the study period. Our disease-free survival rate for early-stage cancer (stage 0-II) was 91% at 5 years. Our study shows that high-quality patient outcomes for breast-conserving treatment can be achieved in the community setting.

RESUMO

PURPOSE: To explore the efficacy and safety of three regimens of weekly paclitaxel plus carboplatin as initial therapy and the feasibility of subsequent maintenance therapy versus observation in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Four hundred one patients were randomly assigned to one of the following arms: arm 1, paclitaxel 100 mg/m2 weekly for 3 of 4 weeks with carboplatin (area under the curve [AUC] = 6) on day 1; arm 2, paclitaxel 100 mg/m2 and carboplatin (AUC = 2) weekly for 3 of 4 weeks; or arm 3, paclitaxel 150 mg/m2 cycle 1 and 100 mg/m2 cycle 2 and carboplatin (AUC = 2) weekly for 6 of 8 weeks. Patients who responded (n = 130) at week 16 were randomly assigned to either weekly paclitaxel therapy (70 mg/m2, 3 of 4 weeks; n = 65) or observation (n = 65). RESULTS: For the 390 assessable patients, the objective response rates observed with initial therapy were 32% for arm 1, 24% for arm 2, and 18% for arm 3. The median time to progression and median survival times were 30 and 49 weeks for arm 1, 21 and 31 weeks for arm 2, and 27 and 40 weeks for arm 3, respectively. The 1-year survival rates were 47% for arm 1, 31% for arm 2, and 41% for arm 3. CONCLUSION: Arm 1, paclitaxel 100 mg/m2 weekly for 3 of 4 weeks with carboplatin (AUC = 6) administered on day 1, demonstrates the most favorable therapeutic index in patients with advanced NSCLC.

RESUMO

We describe the clinical and therapeutic course of a 51-year-old woman with HER-2+ breast cancer who developed leptomeningeal (LM) and spinal cord metastases after 8 years of stable disease on combination therapy with intravenous (IV) trastuzumab. Due to progressive CNS disease, intrathecal (IT) trastuzumab was introduced to enhance HER-2+ therapy into the CSF space. A combination HER-2+ targeted approach achieved clinical remission with stable disease in our patient 46 months after she was diagnosed with LM metastases. However, spinal cord C-1 metastasis was not fully controlled with IT trastuzumab, ultimately leading to the patient's respiratory compromise. In our patient, IT trastuzumab immunotherapy improved prognosis and was an effective strategy to manage HER-2+ LM disease. Given alone or alongside other anti-HER-2+ therapeutics with sufficient CNS penetration, IT trastuzumab could extend the lifespan of patients with leptomeningeal and CNS metastases.

RESUMO

PURPOSE: To test the hypothesis that dual biochemical modulation of fluorouracil (FU) in combination with mitomycin improves the survival of patients with pancreas cancer. PATIENTS AND METHODS: Eligibility included stage II or III unresectable adenocarcinoma of the pancreas, performance status of 0 to 2, and adequate organ function. Treatment included FU 200 mg/m2/d via continuous intravenous infusion for 4 weeks followed by 1 week of rest; leucovorin 30 mg/m2 administered via intravenous bolus infusion on days 1, 8, 15, and 22, followed by 1 week rest; mitomycin 10 mg/m2 intravenous bolus infusion every 6 weeks for a total of four doses. Dipyridamole 75 mg was administered orally three times daily during the FU administration. RESULTS: Fifty patients (median age, 61 years; 23 males, 27 females) with localized unresectable pancreatic cancer were eligible for this trial. Twenty-seven patients survived past 1 year for a 1-year survival probability of 54% (95% CI, 40% to 68%). Overall, the objective response rate was 26% (confirmed and unconfirmed) in the 47 patients with measurable disease, with two complete responders. Six of the responding patients underwent curative successful resection of the tumor. The most common toxicity to treatment was stomatitis. Three patients had reversible hemolytic uremic syndrome. Five patients experienced grade 4 toxicity. There were no treatment-related deaths. CONCLUSION: Potential improvement in survival and resectability of localized unresectable pancreatic cancer may be attained without radiation. The strategy of dual biochemical modulation of FU warrants additional investigation in a randomized fashion.

RESUMO

BACKGROUND: Fine-needle aspiration biopsy (FNAB) is a reliable, rapid, minimally invasive alternative to surgical biopsy when it is performed by physician specialists for the diagnosis of palpable masses. FNAB may be under-utilized in community hospitals in the U.S. because physicians without specialty training commonly provide the service, resulting in less reliable results. METHODS: Records were reviewed retrospectively from 730 consecutive FNAB cases that were performed and interpreted by expert cytopathologists practicing in an outpatient community hospital setting between 2000 and 2004. Data concerning patient demographics, referring physician specialty type, body sites, diagnoses, specimen adequacy, accuracy of diagnosis, and follow-up were examined and analyzed. RESULTS: FNAB was diagnostic in 93% of patients and was 95% accurate. There were 5 false-negative results and no false-positive results for the diagnosis of malignancy. The overall sensitivity of FNAB was 93%, and the specificity was 100%. Using either histology or clinical follow-up, the positive predictive value was 100%, and the negative predictive value was 99%. CONCLUSIONS: Highly reliable results can be obtained when patients are referred to specialty-trained cytopathologists practicing in the community for FNAB of palpable mass lesions. Clinicians are encouraged to seek out and support specialized FNAB services in their own communities.

RESUMO

BACKGROUND: Generally, it is assumed that fine-needle aspiration biopsy (FNAB) for the diagnosis of superficial, palpable masses is a less expensive alternative to diagnostic open surgical biopsy; however, to the authors' knowledge few studies to date have sought to quantify the number of diagnostic surgical procedures avoided and cost savings involved. In this article, the authors report their experience with 664 FNAB procedures that were performed by a cytopathologist/cytotechnologist team practicing in a community setting. METHODS: Records from a total of 664 consecutive FNAB cases from 607 patients who underwent FNAB in a community hospital-based FNAB clinic between 2003 and 2005 were reviewed retrospectively, and follow-up data were obtained. RESULTS: Surgery was averted entirely as a result of the FNAB in 83% or 505 of 609 cases with follow-up available. The FNAB procedure was highly accurate and considerably less expensive than surgical biopsy. CONCLUSION: For patients who presented with palpable masses, FNAB was a reliable, cost-effective initial method for obtaining a tissue diagnosis.

RESUMO

BACKGROUND: Administration of paclitaxel on a weekly schedule in combination with carboplatin is associated with a lower incidence of neuropathy and myelosuppression. The authors conducted subgroup analysis of their randomized phase II study of three different schedules of weekly paclitaxel with carboplatin to determine the efficacy of each regimen in elderly patients (aged > or = 70 years) with advanced non-small-cell lung cancer (NSCLC). METHODS: Patients with advanced NSCLC were randomized to one of three different weekly paclitaxel/carboplatin regimens. After four cycles of chemotherapy, those with objective response or stable disease were randomized to weekly paclitaxel or observation as maintenance therapy. Four hundred three patients were enrolled in the study, of whom 111 (28%) were aged 70 years or older. RESULTS: The treatment regimen of weekly paclitaxel (100 mg/m for 3 of 4 weeks) and carboplatin (area under the curve = 6 mg/ml/min once every 4 weeks) (arm 1) was associated with the best therapeutic index overall. The median survival and 1-year survival rates were 11.3 months and 50% for patients in the > or =70 years cohort versus 11.2 months and 46% for the <70 years cohort in arm 1. Efficacy results were comparable between the two groups in the other arms as well. Grade 4 neutropenia and febrile neutropenia occurred in 13.6% and 2.3% in the > or =70 years cohort compared with 4.5% and 1.1% in the <70 years cohort in arm 1. CONCLUSION: The weekly regimen of paclitaxel administered in combination with carboplatin is tolerated well by elderly NSCLC patients and has comparable efficacy with younger patients.

RESUMO

This article describes a woman with metastatic upper gastrointestinal cancer who developed thoracic myelopathy unexpectedly after standard dosage and fractionation radiotherapy. She also was receiving capecitabine and gemcitabine concomitantly. There are few reported cases of chemotherapy potentiation of spinal cord radiation toxicity. These agents are known radiosensitizers, making it likely that they contributed to this adverse outcome. As these agents are increasingly incorporated into clinical trials of combined therapy, caution will be necessary in both trial design and clinical management.
